[PATCH net-next 3/3] virtio-net: clean tx descriptors from rx napi
...I suspect that even with the cache invalidations this optimization
will be an improvement over handling all tx interrupts in the tx napi
handler. I will get the datapoint for that.
That said, we can make this conditional. What flag exactly do you
propose? Compare raw_smp_processor_id() in the rx softint with one
previously stored in the napi tx callback?

I'm not sure. Another idea is to check vi->affinity_hint_set.
If set we know rq and sq are on the same CPU.
